SPECIFICATION forming part of Letters Patent No. 414,410, dated November5, 1889. Application filed August 22, 1889- Serial No. 321,583. (NomodeL) To all whom it may concern:

Be it known that I, ALBERT HENLEY, of Lawrence, in the county of Douglasand State of Kansas, have invented a new proved BaleTie lowing is afull, clear,

The objectof the invention is to provide a new and improved machinewhich is simple and durable in construction, very effective inoperation, and specially designed to manufacture bale -ties of wire forbaling hay, straw, &c.

The invention consists of certain parts and details and combinations ofthe same, as will be fully described hereinafter, and then pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Fig. 6 isan enlarged sectional side elevation of the same on the line .2 2 ofFig. 3, looking in the direction of the arrow 2'. Fig. 7 is an enlargedplan view of the tail-piece of the machine. Fig. 8 is a transversesection of the same on the line 10 w of Fig. 7. Fig. 9 is a like view ofthe same on the line i" v of Fig. 7. Fig. 9 is a detail perspective viewof the mechanism for sliding the shaft N Fig. 9. Fig. 10 is a similarview of the same on the line a u of Fig. 7. Fig. 11 is an end elevationof the same. Fig. 12 is an enlarged transverse section of the cylinder,and Fig. 13 is an enlarged end elevation of the feed-rollers.

The improved bale-tie machine is provided with a suitably-constructedframe A, on one end of which is mounted a head B, and on the other endis held a tail-piece 0, between which and the said head B is held thecylinder D, carrying the bale-tie during the process of twisting one endthereof. On the head B is mounted to turn in suitable bearings the maindriving-shaft E, carrying the usual pulleys connected by belts withother machinery for imparting a rotary motion to and Im-' Machine, ofwhich the fol-' and exact description.

the said main driving-shaft E. On the latter is secured a groovedfeed-roller F, above which is located a similarlygrooved feedroller F,and between the two feed-rollers is passed the wire G to be formed intoa baletie. The feed-roller F is secured on a shaft F which carries agear-wheel F adapted to mesh into a similar gear-wheel F secured on themain driving-shaft E, so that when the latter is rotated the twofeed-rollers F and F travel together and move the wire G forward. Theshaft F is mounted to turn in suitable bearings formed on a frame F,pivoted at one end, at F to the frame of the head 13. In the frame F isalso formed an aperture F through which passes the wire G, and as theframe F is mounted to swing itcan be swung upward, so that the wire G ismoved out of contact with the feed-roller F on account of passingthrough the aperture F of the said frame F, whereby a forward feeding ofthe wire ceases.

On the outer E is secured a gear-wheel E, which meshes into a largergear-wheel E mounted to turn on a stud E secured on an arm E fulcrnmedon the main driving shaft E and provided with a bolt E adapted to besecured in any desired position in the slotted segment E held on theframe of the head B. The larger gear-wheel E carries on one face apinion E meshing into a gear-wheel E fastened on atransversely-extending shaft H, mounted to turn in suitable bearings inthe frame of the head B. On this transversely extending shaft H issecured a cam-wheel H, (see Fig. 6,) on the periphery of which rests thefree end of the frame F, so that when the shaft His rotated the saidcam-wheel H alternately raises and drops the free end of the framcFwhereby the feedrollers F and F are alternately thrown in and outofcontact with each other. During the time the feed-rollers are thrown outof contact the wire G remains at a standstill, and during the time thatthe feed-rollers remain in contact the wire G is fed forward, aspreviously described. The speed of the shaft H can be increased ordiminished by placing a differentsized pinion E on the arm E" andchanging the latter accordingly on the slotted segment E The wire G,before passing into the frame F and to the grooved rollers F and F,passes througha se end of the main driving-shaft 1 ries ofvertically-arranged friction-rollers I and a series ofhorizontally-arranged frictionrollers I.

On the transverse shaft H is secured a bevel gear-wheel H meshing into abevel gearwheel H secured on the longitudinally-extending shaft Hmounted. to turn in suitable hearings in the frame A and extending fromthe headB to the tail 0. The shaft H operates the mechanism J (see Fig.5)for turning the cylinder D one quarter-turn at certain intervals. ThemechanismJ is provided with an almond-shaped cam'J, secured on the saidshaft and operating on a lever J fulcrumed at one end to the main frameA. The free end of thelever J is pivotally connected by a link J 3 witha crank-arm J fastened 011 one end of the shaft J 8 of the cylinder D. Aspring J 5 is also connected with the free end of the lever J and servesto press the said lever into contact with the periphery of thealmond-shaped cam J. On the crank-arm J 4 is held a spring-pawl J",adapted to engage one of four notches formed in a disk J secured on theshaft J of the cylinder D. The notched disk J is adapted to be engagedby a spring J serving to hold the cylinder D in the proper positionuntil turned by the return movement of the. mechanism J. When the shaftH revolves, the cam J acts on the lever J and throws the latter outward,so that a swinging motion is imparted to the crank-arm J whereby itspawl J 6 turns the disk J and the shaft J 8 of the cylinder D is turnedone quarter-turn, the spring J 9 dropping at its free end into the nextfollowing notch. During the other half-motion of the cam J the pawl J 6rides over the disk J which latter is held in place by the spring J Theshaft H also imparts motion at the proper time to the cutting mechanismK, provided with two knives K and K located opposite each other, and ofwhich the knife K is stationary, being held in suitable bearings in theframe of the head 13. The other knife K is held in a frame K mounted toswing on the frame of the head B, and provided with an arm K resting onthe periphery of the cam K secured on the shaft H. A spring K pressesagainst the frame K so as to hold the arm K of the latter in contactwith the periphery of the cam K When the latter is in the position shownin Fig. 4, the knives K and K are apart and permit the free discharge ofthe wire G. however, turns, the arm K is swung outward by the cam K sothat the frame K swings on its fulcrum and moves its knife K toward theknife K so that the wire G between the knives K and K is cut. Duringthis operation the feed-rollers F and F are out of contact with eachother, and the wire G remains stationary. The knives K and K arepreferably held adj ustably in their respective bearings by suitablebolts or other means, so as to sharpen the knives whenever necessary andto compensate for the wear on the sharp edges of the knives.

The cylinder D, into which the wire G is fed, is provided with fourlongitudinally-extending arms D, each provided on its outer edge with agroove D extending longitudinally and adapted to receive the wire G.Each ,groove D is covered by a plate D held to slide on the outer end ofeach arm D and secured in place by a series of bolts D passing throughinclined slots D in the said plates D held a pin D, adapted to engage acam D secured on the main frame A, and serving to shift the cover-platesD when the respective arm D is in its lowermost position, so as touncover the respective groove'D to permit the dropping out of the wire,as is plainly shown in Fig. 12. When the lowermost arm D again movesupward on the turning of the cylinder D, the cam D again shifts therespective cover-plate D until the respective groove D is again closed.

The wire fed into the cylinder D projects a suitable distance-about sixinchesand passes through a clamping device L to a bending device N and atwisting device 0, which double theouter end of the wire to form a loopG and a twist G in the wire G, as shown in Fig. 2. The three devices L,N, and O are located on the tail 0 and are actuated from the shaft Hpreviously mentione The clamping device L (see Fig. 10) is provided witha bent lever L, fulcrumed at L I11 the middle of each plate D is on abracket C secured on the frame 0 of the tail 0. One end of the lever Lis provided with an inwardly-extending offset L adapted to'clampthe wireG on a fixed anvil L formed on the bracket'C The other end L rests onthe periphery of a cam L'gsecured on the shaft H so that when the latteris rotated the lever L is swung and its projection L moves inward anddownward, clamping the wire G on the anvil L The bending device N (seeFig. 9) is provided with a disk 'N, from which projects a crank-pin Nadapted to double up the end of the wire projecting beyond the cylinderD. The disk N is secured on a shaft N mounted to turn and to slideinsuitable bear ings formed in the frame 0 of the tail 0. On the shaft Nis held to turn and to slidea gear-wheelNfl meshing into asegm entalgearwheel N fastened on an arm N fulcrumed on the tail-frame C. Near themiddle of the arm N is held a pin N engaging an elliptical cam-groove P,formed in the cam P, fastened on the shaft H WVhen the latter isrotated, said cam P imparts a swinging motion to the arm N so that itssegmental gearwheel N turns the gear-wheel N forward and backward,whereby the shaft N with its disk N, is turned for doubling the wireend. The shaft N 3 is mounted to slide transversely, so

as to disengage the pin N from the doubled the loop is made. Forthispurpose,

end after the mechanism Q is provided, comprising a grooved collar Q,secured on the rear end of the shaft N and engaged by one end of a leverQ fulcrumed on the tail-frame O,and engaged at its other end bya cam Qsecured on the shaft H". A spring Q serves to hold the lever Q incontact with its cam Q. hen the shaft 11* is turned, the cam Q imparts aswinging motion to the lever Q whereby the collar Q is moved.transversely, and a similar motion is imparted to the shaft N so thatthe pin N is drawn out of contact with the wire G.

The twisting device 0 operates in conjunction with the bending deviceN,'and is provided with a pin 0', located in front of the pin N whichlatter bends the end of the wire G over the pin O when the disk N isturned; The pin 0 is secured on a shaft 0 extending longitudinally andmounted to turn in suitable bearings on the tail-frame C.

On the shaft O is secured a pinion 0 (see Figs. 7 and 8,) in whichmeshes the segmental gearwheel 0', fastened'on an arm 0 fulcrumcd on thetail-frame O and provided with a pin 0, engaging an ellipticalcam-groove 0 formed on one face of the cam Oisecured. on the shaft H.\Vhen the latter is rotated, the cam O imparts a swinging motion to thearm 0 so that the segmental gear-wheel 0 turns the gear-wheel 0 forwardand backward, whereby the pin 0, having holdof the loop of the bentwire, forms the twist G" when the shaft 0 turns in one direction. WVhenthe shaft 0 is at the end of its movement in one direction, the pin Ostands downward, so that the loop G of the wire G can drop 01f of thepin 0', after which the shaft 0 is returned to its former position.

At the end of thetail C is located a registering or counting device R,provided with a bevel gear-wheel R, secured at the end of the shaft Hand meshing into a bevel gear-wheel R fastened on thetransverselyextendin g shaft R mounted to turn in suitable bearings onthe tail-frame C.

On the shaft R is securedaworm R meshing into a worm-wheel R mounted toturn on a stud secured on the tail-frame C. On the outer face of thesaid worm-wheel R is held a cranlcpin R, adapted to engage a pin S,fastened on a lever S,fulcrumed at its upper end on the tail-frame O andpivotally connected at its lower end by a link S with alever S fulcrumedon a shaft T, mounted to turn in suitable hearings on the frameA andextending longitudinally under the cylinder D, as is plainly shown inFig. 2. The other end of the lever S carries a spring-pawl S engaging anotched disk secured on the said shaft T and held in place by a spring Tas is plainly shown in Fig. 11. A spring S presses on the lever S tohold the same in an innermost position. v

011 the shaft T are secured two or more sets of hubs carrying radialarms U, adapted to rethen passes between the feed-rollers F and F,

which feed the wire forward past the knives K and K in the groove D 011the uppermost arm D of the cylinder D. The wire G passes through theentire length of the cylinder D and projects at the tail 0 about sixinches. At' this moment the cutting mechanism K cuts off the wire bymeans of the knives K and K and at the same time the frame F is swungupward by the action of the cam H on the shaft H, so that the wire Gremains at a standstill. The piece of wire held in the cylinderD nowturns with the latter, said cylinder making one quarter-turn by theaction of the turning device J, previously described. The projecting endof the wire in the cylinder D and tail O now passes onto the top of thepin N of the disk N, and at the same time the shaft 0 turns, so thatvits pin 0" passes over the projecting end of the said wire, as is shownin Fig. 7. The disk Nnow turns so that the pin N bends the wire over thepin 0' and passes the end of the wire between the lever L and the anvilL onto the wire already on the anvil L as shown in Fig. 10. The cam Lnow acts on the lever L, so that the offset or foot L clamps the twoparts of wire onto the anvil L The mechanism Q, after imparting atransverse sliding motion to the shaft N is now actuated by the cam Q sothat the said shaft N slides rearward and the pin N is disengaged fromthe doubled-up end of the wire. to the shaft 0 from the shaft H by meansof the cam 0 the arm 0 the segmental gearwheel 0 and the pinion 0 sothat the pin 0' twists the end of the doubled wire, so as to form theloop G and the twist G (Shown in Fig. During this time a new piece ofwire G fed into the top arm of the cylinder 1) is cut off by the cuttingmechanism K, and a quarter of a revolution is again imparted to thecylinder D, so that the first finished wire passes with the arm 1) ofthe cylinder Dinto its lowermost position, and during this quartermovement of the cylinder D the cam D opens the cover-plate D, so thatthe finished bale-tie drops out of the arm D and falls between twocorresponding radial arms of the sets of arms U. The above-describedoperation is then repeatedthat is, the wire is fed into the uppermostarm, cut oif, the cylinder is turned one-quarter of a revolution, theloop and twist G and G of the cut-off wire in the cylinder D are formed,a new piece of wire is inserted into the top of the cylinder, and thelowermost finished bale-tie is dropped out of the cylinder, as abovedescribed.

The registering device R is so arranged that the sets of arms U remainin position until,say, one hundred bale-ties have been dropped betweentwo corresponding arms.

A rotary motion is now imparted Then the pin R acts on the pin S, sothat the lever S actuates the lever S which latter, by means of itsspring-pawl 8*, turns the shaft T so as to bring the next following setof arms U directly under the cylinder D. Thus one hundred bale-ties arealways placed between the corresponding arms U of a set and droppedsimultaneously on the floor or are otherwise removed from the said arms.
